I read a post on another site about a toddler that had anemia related to B12 deficiency. B12 deficiency can happen when there’s not enough acid in the stomach to absorb the B12 because of chronic PPI use. This can be very dangerous and become life threatning. I asked my doc. about this and he said that it’s more common in adults but a B12 check isn’t a bad idea. We’re going to have Evan check next week. He’s been on PPI for almost 3 years now
